de dos proyectos venideros de CC de alta tensión (HVdc) con
objetivos únicos.
El primer proyecto es un sistema de HVdc de convertidor conmutado por línea (LCC) a escala de gigavatios, que
conecta redes nucleares masivas con un área metropolitana.
Este proyecto reemplazará uno originalmente planeado
para transmisión de 765 kV que enfrentó una fuerte oposición pública debido a preocupaciones de emplazamiento.
El diseño del proyecto de HVdc ofrece ventajas medioambientales, técnicas y de políticas públicas al tiempo que
también cumple con los estándares de rendimiento de confiabilidad.
El segundo proyecto consiste en una conexión VSC-HVdc basada en un convertidor multinivel modular (MMC)
entre el continente y la isla de Jeju. Este proyecto entregará
un flujo de potencia bidireccional y se coordinará con dos
vínculos de LCC-HVdc existentes.
Los dos nuevos proyectos de HVdc requieren de estrategias de funcionamiento complicadas y novedosas. Por lo tanto,
se deben llevar a cabo estudios exhaustivos de viabilidad que
superen el alcance de los que normalmente se llevan a cabo
para la tecnología convencional. La empresa de servicios eléctricos Korea Electric Power Corporation (KEPCO) y las universidades asociadas consideraron muchos métodos y herramientas de planificación y simulación avanzados para lograr
soluciones prácticas y creíbles de manera eficiente y precisa.
Este artículo presenta los problemas y desafíos inminentes para el desarrollo del futuro sistema de energía eléctrica

Linea de transmisión

de Corea del Sur, los procedimientos utilizados para mejorar
la aceptación pública de los proyectos y los estudios llevados
a cabo para abordar los problemas de estabilidad del sistema
eléctrico. El artículo también describe metodologías innovadoras para mejorar la precisión de los resultados de planificación del sistema energético, así como la identificación de
actualizaciones de planificación que aumentan los niveles de
transferencias del sistema energético.

Infraestructura única del sistema
energético en la República de Corea
El sistema de potencia de la República de Corea, que se
muestra en el gráfico 1, está completamente aislado de los
países vecinos debido a problemas políticos y geográficos.
Su consumo de electricidad per cápita fue de 10,320 kWh/
cápita en 2017, lo que supera al de la mayoría de los países europeos que tienen áreas terrestres relativamente más
grandes [véase el gráfico 2(a)]. Debido a la gran cantidad
de generación y consumo eléctrico en relación con la población [véase el gráfico 2(b)], las instalaciones de generación
y transmisión en la República de Corea están densamente
cargadas, con pocas oportunidades para nuevos terrenos
rurales. Además, la relación de carga máxima con respecto
a la capacidad de generación es alta, como se muestra en el
gráfico 2(c).
El complejo de mayor generación (en la costa este) y el
centro de carga (alrededor de la capital, Seúl, en el noroeste)
están aproximadamente a 350 km de distancia y están
